MILK cooLEB.

Applicationfiled September 7.192s. Serial No. 804,604.

This invention relates to a deviceforcooling bottles of milk by theevaporation process. The principal objects of the lnvention are torovide a Cooling device whlch Wlll be simp e and convenient to operateand can beused over and over again and which can be put out-doors atnight, located oneside up, so that the liquid will not leak out, and canbe turned over a milk bottle in the morning without the manipulation ofany valves or other devices and will apply to the outside of the bottlea cooling medium in such form that it will evaporate and keep the bottlecool for several hours. Also to provide a container for the water inco-operation with a distributor cup which, when inverted, will supply anabsorbent medium with the necessary liquid.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings in which Fig. 1 is aside view of a preferred form of the device shown in position over amilk bottle;

Fig. 2 is a diametrical sectional view thereof;

Fig. 3 is a similar sectional view of the device shown in its positionwhen not in use; and Y Fig. 4 is an elevation showing another way inwhich the device can be applied to. an empty bottle ready to be invertedover a new bottle when it is delivered.

It .is customary to deliver milk bottles in exposed places where theyarelikely to receive the rays of the sun for several hours before they; aretaken in. This invention is designed for the purpose of cooling the samefor several hours until such time as the bottles may be taken in, butthe invention is capable of use for cooling purposes under. otherconditions and under other circumstan'ces.

The cooler consists of a cylinder 10 of textile material such as canvas,felt or the like which, for the purpose of stiffening it, is providedwith a casing 11, preferably of skeleton form, to which the cylinder 10is secured at the top and bottom if desired. At, any rate, the skeletonframell, which can be formed of sheet metal, for example sheet aluminum,can be provided with wide openings therethrough which will furnish astiffener for the fabric andho'ld it in place as shown in Fig. 1.This'cylinder 10 is formed The fabric shown at 10 extends to ofabsorbent material for the purpose of receiving water .or other liquidand readily evaporating. it to keep dowri the temperature of a milkbottle to whichit is applied.

In the position shown in Fig. 1, it has at the top a distributor 12,which consists of a cup-shaped piece of metal having fine perforationsaround it near the top and other perforations lower down but spacedfarther apart so as to reduce the amount of liquid flowing out of itafter the absorbent material is first soaked. It alsohas a neck 13 whichis cylindrical outside and registering with the skeleton casing 11, thatis, nearly the same diameter, and provided with aninternal screw thread.Into this screw thread fits the end of a cup 14 which is the sameexternal diameter ust mentioned. These.

parts can be formed of aluminum orother metal, as may be convenient andinexpensive. the end of the skeleton casing 11.

In the use of the device, it is turned up in the position shown in Fig.3,,liquid is placed in the .cup'l l, which preferably is filled to 1 itstop level, then the distributor cap 12 is screwed down on it, and thetextile cylinder 10 is. put down over that with the casing 11 outsideit. These parts fit well enough so that they will stand in thatposition, as shown in Fig. 3. If desired, the metallic casing 11 can beprovided with a hook l6 and the device can be supported on an empty milkbottle, as indicated in Fig. 4,

depending from the hook. In this case, the parts 10, 11 and 12 have tofit each other with enough friction to prevent the filled with liquid,from drop in Ineither this form or in t e orm' shown cup, when in Fig.3, the cup 'is filled and put out with the empty milk bottles at. night.In the morning the new milk is delivered and the milkman turns thisdevice bottom side up. and puts it over the fresh bottle of milk.

The result of' this is that the liquid oozes out the perforations in thedistributor 12 and at first a large amount of liquid comes "out at thetop and soaks the textile cylinder 10 so that it will be thoroughlywet.,

bottle of milk, which is. already cooled, will thus-be kept cool aslongas this evaporation.
